FARE -- Compact Spinning of Staple Fibers.

Compact spinning lines for staple fibers range in capacity from 10-50 tons per day and permit frequent changes in denier and color. Drawing, crimping, and cutting operations are integrated into these lines. Compact spinning is slower than conventional spinning because of these integrated operations. Increasing the number of holes in each ..

Theoretical and Experimental Studies on Fiber Processing

An experment examined the melt spinning process for sources of instability, focusing on the phenomena of draw resonance and disturbance amplification. An analysis of nonlinear draw resonance dynamics during isothermal melt extrusion yielded equations for Newtonian, exponential, and viscoelastic fluids. The equations quantified the relatio..

Cotton: World Markets and Trade.

The United States Department of Agriculture (USDA) presents its February 1995 estimates of world cotton production, consumption, and trade. The USDA estimates that world cotton production for the crop year 1994-1995 will be 84 million bales. The United States cotton production for the crop year 1994-1995 will be approximately 19.7 million..

The World of Staple Fibers.

Most of the volume generated by staple fiber production is manmade staple fibers, but wool and cotton are also importnat staple fibers worldwide. The major objective of manmade staple fiber production has historically been to simulate natural staple fiber properties. Cotton and woolen processing systems typically process both natural and ..

Cotton Rides a High Tide of Popularity.

The National Cotton Council's 1995 Beltwide Cotton Production Conference attracted a record 5,000 participants. In 1985, the United States cotton crop reached its lowest level at 8.4 million bales. In 1995, the United States cotton crop will exceed 19.5 million bales, the largest crop since the 1937 crop of 34 million bales. High volume i..

료셀 섬유

비스코스 섬유를 제조하기 위해 새로운 용제에 기초하여 개발된 공정을 정리하여 나타내었다. 일반적으로 료셀이라고 알려져 있는 새로운 섬유는 미국에서 텐셀이라는 상표명으로 생산되고 있다. 1996년 하반기에는 서부유럽에서 생산이 이루어질 것이다. 관련 기술이 소개되어 있으며, 피브릴화에 있어서의 문제점 최종 용도, 제품의 레이블 및 렌징사와 코틀즈사 ..

더 강한 료셀 섬유

높은 비강도를 지닌 료셀섬유는 Courtaulds Fibres사에 의해 처음으로 시장에 나타났다. 이 섬유는 원면보다 더 높은 습윤 강도와 높은 초기 습윤 모듈러스를 가지므로 습윤시 일지라도 낮은 수축율을 가진다. 높은 온도에서 이 섬유의 사용이 흥미를 끄는 것은 비열가소성(non-thermoplastic) 성질때문이다. 각각의 극세섬유(피브릴)들이 주섬유들과 단단히 연결되..

Recycling of Polypropylene Carpeting Waste. Part Ⅰ. Feasibility Study.

A research project examined the feasibility of recycling polypropylene carpeting waste into a meltable, thermoformable backcoating. The backcoating would be used in polyester carpeting utilized as molded automobile trunk linings. The investigation considered the recycling of two different polypropylene floor coverings: carpeting that cont..
